Network Speed: raspberries Vs bananas


Many of us want to use the *Raspberry Pi* to build a *NAS, DLNA server, Samba shared folder* or any project that makes heavy use of the network. Sometimes we forget about the limited *Raspberry Pi* capacity of bandwidth that has the *Ethernet* port and we forget alternatives like the *Banana Pi*.

*Frank Mankel* is a user of a *Google Plus* community on [BPi](https://plus.google.com/communities/116770564125019694131) and shows us how quickly he test it using *iperf*. Let's see the results of a file transfer over the network...

The file used has *3.1GB* from a shared folder with *NFS* to a *IntelNUC* with the following results:

1. BananaPI 1 to my IntelNUC DC3217IYE
2. BananaPI 2 to my IntelNUC DC3217IYE

The transfer was completed in **1:03**, which are approximately **50 MB/s**. Remember that the speed with the Pi is about *6-8 MB/s*. What do you think?
